\ i This invention relates H to'` improveinents in a separable pipeline connection for? a `blasting ,cartridge and is `particularly ap-`V plicablefforuse in' connection with apparatus @3^ used `ina systeingof blastingsuch as disclosed A 1,569,226 issuedV n present invention vvillbe more readily apinour former Patent No. January l2,` 1926.`

As disclosed in ouriformer patent, `vve oemploy al A blastingY cartridge consisting)` of a for rigid container; Vor shell` having associated therewith la rupturable `vvall and havingrcon-"i nefeted` thereto,y apipe line from n asource of; pressure.` The apparatus i is used by 1' placing i the,` blasting' cartridge lin f a *drill holei andf delivering to the blastingoartridge through :i

the" pipe line ,under high" `pressure an eX- pansble gas Wherebygvvhen theurupturable Vpressure israched, the gas `is released frorin n thejlblastingi'cartridge and expands J inizlthe. material to :beyblasted thereby breaking dovvn the material.; As disclosed in our ap+ 193% construction imayrbe usedinwhichtheg,

The pipeline 2 6,` a'sshovvn Figures@ W and is protected bya flexible armoured 96" covering 34 and the releasable connection 28 which connects the pipe line 26 yto the blasting cartridge 22 is so designed that a tensile pull Y will separate the pipe line from the blasting cartridgewith'out injury to the parts, or in.'VV

such manner that it is only necessary to insert a renewable'p'art to make a new connection. In Figure 2 the endl of the pipe line 26 is flanged or beaded as at 36,'and is clamped by .10 the Vnut 38 threaded into the tubular shell 40 against a sealing ring 42. A short tubular iece 44 is secured tothe blastingfshell 22 y thev fnutf 46 threaded into vthe Ishellfand,

. clamping the beaded end 48 of the. tube 44 threaded into oneend of the shell 40'.

It will bei readily understoodrthat by adjusting thenut 56,*the force required to sep- 9i{s arate the pipe 26 Jfrom the pipe 44 by tensile ""pull, may 'be varied and Vin order toV make a new connection it isl only necessary to release 1 the :nut..56. topermitrthe reinserti'on of the whichv may be developed, due toitheffact that.

in the ,further modification@ .Figure i,l

there is shown a pair-of co-axiallyvdisposed nuts`68 and 7 4 having extending therethrough a tube-72 which is beaded at its end as at 70 and 7 6, allfof which is similar to the arrangement in Figure 3. However, in Vthisiorrn,V Vone of the nuts is formed with asocket 8O adapted to receive a projection 82 from the other nut. TheV nuts are therefore connected by a socketl joint which prevents injury to the tube 72 which is preferably of'sot materialY such as copper by lateral movement of the nuts;` Therefore, duringlthe handling of the. releasable connection'ff as ythus made up,v
